In carrying out the inven-rcommonly used in line casting .machines comtion, the ordinary flat lineris adapted to carry a prising a mold body and mold cap and liners stopshaped to correspond to that of the extended interposed between the bodyand cap and definor recessed front portion of the mold'cavity to ing thelength and the height of the mold cavity stop olT the length thereof,such stop being deand hence the length and thickness of the slugstachable from the liner or otherwise removable 10 cast therein. from itsoperative position thereon so that the Molds of this kind have beenequipped with same liner may be used interchangeably for molds plainsurfaced caps for the casting of ordinary with recessed caps for castingslugs with extended flat-sided or solid slugs and with recessed capscharacter bearing edges or for molds with the for the casting ofskeleton slugs having relatively usual plain or solid caps for castingordinary 15 large or extended type characters thereon. Such slugs, thusavoiding the expense of carrying stocks liners may be used fordetermining the length of two different types of liners in all sizes. ofthe mold cavity and the spacing of the body In the accompanying drawing,which show the and cap of a mold for casting the ordinary solid p fer dembodi ents of t e invention: slugs which are of the smaller sizes, andthe re- Fi 1 s a f o t elevation o a m d for line 20 cessed cap of amold may be spaced from the body casting machines, provided with a linerembodythereof by inserting liners of different thicking the presentinvention for determining the nesses between such mold cap and body, oneat length of the mold cavity; each end, and by using liners of diiferentlengths F ure 2 is a p rsp t v w of a yp ar or at one end of the mold,the length of the main slug of the skeleton form and having an extended25 or body portion of the mold cavity may be varied.

The primary object of the present invention is Figure 9 i a View Similar3 but Showing to provide means whereby the ordinary fiat liners the stopin inoperative position for use in ordinary commonly used for moldsemploying plain caps m lds for cast ng rdinary flat-sided or solid forcasting solid small bodied slugs of different u V lengths may be adaptedfor use with recessed Similar parts are designated y h sa e refmold capsfor stopping off the main portion of erence characters in the differentfigures. the mold cavity and also the extended or recessed The mold asshown in Figure 1 Comprises front portion thereof in which the extendedusual an upper part or cap 1, a lower part or body 2 and the left handand right hand liners 3 and 4, respectively, which space apart the capand body members of the mold to form the continuous casting cavity 5which is stopped off or closed bythe inner ends 6 and. 'lof theseliners. The lower or casting face of the cap 1 is formed at intervals inits length with grooves 8 which extend upwardly from the casting cavity5 and form the ribs 9 on the body portion 10 of the slug, as shown inFigure 2, and the front of the cap is bevelled to form a recess 11which. is extended upwardly from the cavity 5 at the front or matrixengaging edge of the mold, the extended character bearing edge 12 of theslug as shown in Figure 2 being cast in this recess.

The cap 1, however, has the recess 11 formed therein of a lengthsuitable for the casting of a adaptor forv the ordinary liner 3, which,when applied thereto, will serve in conjunction therewith toiorm acomplete closure for the respective end of the entire front of the moldcavity. In carrying out the, invention as shown in Figure 3, theordinary fiat liner 3, which determines the length of the mold cavity,is provided near its inner end with an aperture 13, and a stopin theform, of a block 14 is provided which is beveled on one side andotherwise shaped to fit into the recess 11 in the front edge of the moldcap and to correspond in cross section with said recess, this blockhaving a stem 15 thereon adapted to be removably inserted in theaperture 13 in the liner, so that when applied to the liner and thelatter is inserted in a recessed mold as shown in Figure l, the innerend 6 of the liner will stop off or close the main portion 5 of the moldcavity and the block 14 will stop off or close the recess 11 evenly withthe inner end 6 of the liner.

In the embodiment of the invention shown in Figures 5, 6 and 7, therecess 11 in the mold cap l is square or rectangular in cross section sothat it will. cast a correspondingly shaped extended part 12* on theslug as shown in Figure 'Land the liner 3 is adapted to receive a block14 of corresponding rectangular form to fit into and conform in crosssection with the recess 11 the block i l having a stem 15 to removablyfit into the aperture 13 in the liner 3, as in the form of the inventionshown in Figure 3.

In the embodiment of the invention shown in Figures 8 and 9, the stopblock 14 is of a thickness equal to the thickness of the liner. 3 and isrotatably connected thereto and fitted in a recess 3*? in the front edgeof the liner by a pivot pin 3 sothat this block may be swung upwardlyfrom the plane of the liner as shown in Figure 8 so that it, will fitinto and stop oif the recess 11 in the mold cap when the liner is usedin a mold having such recessed cap, and this block may be swungdownwardly into the plane of the liner as shown in Figure 9, thusadapting the liner for. use in a mold having an ordinary plain orunrecessed mold cap for the casting of ordinary slugs. The block lfl maybe exchanged for one of a diiferent length, for which purpose it isremovable from the pivot pin 3.

In each'instance, the stop block may be used with liners of differentlengths and thicknesses.

'; By providing the aperture 13 in the ordinary fiat mold liner, anyshape of stop block to conform with a beveled, square or other shapedrecess in the front of a recess mold cap can be employed in conjunctionwith such liner and thereby render the liner suitable for use in varyingthe length of the slugs cast in such molds. The presence of the aperture13 in any liner obviously will not aiiect the utility or" the liner forthe ordinary plain or flat surface mold cap for casting solid bodiedslugs. The provision of the stop block as a liner adaptor obviates thenecessity of carrying special liners for recessed mold caps, or thenecessity of employing mold caps recessed to different lengths in orderto secure diiierent length I slugs of the skeleton form.

I claim as my invention:-

1. A mold for line casting machines having liners for determining thelength of the slug body casting portion of the mold cavity, at least oneof the liners carrying a stop formed separately therefrom andcorresponding inshape with a recessed front part of the mold cavitysuitable for casting slugs with overhanging type faces to limit thelength of said front part of the mold cavity.

. 2. A mold according to claim 1, wherein said stop is exchangeablyconnected to the liner.

3. A liner for determining the length of the slug casting cavity of themold of a line casting machine, and a stop carried by said liner andcorresponding in shape with the recessed front part of the cavity ofa'mold for casting slugs with overhanging'type faces, said stop beingadapted to occupy a position on the liner to limit the length of therecessed part of the mold cavity liners for determining the length ofthe slug casti ing cavity therein, one of the liners having a thicknessequal to the height of the slug body casting portion of the mold cavity,and a stop carried by the liner of a shape to conform with and fit intoa recessed portion at the front of the moldcavity for casting anoverhanging character bearing portion on the slugs, to limit the lengthof said recessed portion, and removable from said position to adapt theliner to an unrecessed mold cavity.

'7. In or for a line casting machine mold, liners for determining thelength of the slug casting cavity of a mold of uniform'height throughoutits length, and means associated with at least one of said liners forcarrying a stop formed separately therefrom, said stop corresponding inshape with a recessed part of a mold having a cavity suitable forcasting slugs with overhanging type faces and said stop being operativeto limit the length of the recessed part of said last mentioned mold'.

8. In or for a typographical machine, a mold having an unrecessedcasting cavity, a mold having a recessed casting cavity, end linersnormally operative to limit the length of said unrecessed mold cavityonly, and means for rendering said liners selectively operative to limitthe length of either of said mold cavities DAVID L.
